Celebrate all things bling in Shadow Diamond, a 5 reel, 40 payline, jewellery themed slot from Bally Technologies. This sparkly offering comes with super stacked reels and a free spins bonus round. Play from between 80p and £400 per spin.

As you’d expect from a title called Shadow Diamond, the reels are packed full of shiny imagery. Look out for diamond rings, necklaces and jewel-encrusted watches as well as a selection of brightly coloured gemstones (rubies, emeralds, sapphires). The Shadow Diamond logo is the wild and substitutes for all other symbols apart from the scatter.

The glamorous man and woman are the biggest payers from the standard symbols, offering payouts of 40 and 50 times your line bet respectively if you find a 5 symbol combination. They may seem a little skinny but things improve on the payouts front thanks to the stacked symbols.

Before each spin, 1 of the symbols will become the nominated Super Stack. The chosen symbol can then appear fully stacked and fill up an entire reel or even better reels. If you manage to fill up multiple reels with the same stacked symbol some impressive payouts will be in the offing. All of the symbols can appear stacked in all 5 reels apart from the scatter which only appears stacked on reels 2, 3 and 4.

When the diamond scatter does appear stacked on reels 2, 3 and 4 it will trigger the Free Spins feature – here you’ll be awarded 7 free spins. Before the round begins, you’ll have to choice which 1 of 5 symbols will be the Super Stack. All of the mystery symbols are replaced by your pick, boosting your chances of a win. Unfortunately, you can’t win more free spins.

For a slot with such a glitzy theme, the visuals are slightly underwhelming. They’re perfectly serviceable but look a little dated compared to the glossy, HD visuals appearing in many modern-day online casino releases (think NetEnt’s Mega Fortune Dreams).

Shadow Diamond is pretty simple in the features department too – the SuperStacks keep the pace flowing nicely but the free spins are pretty difficult to trigger. However, the variance in Shadow Diamond is high.

Expect some fallow periods with few wins but watch out for the Super Stacks as the wins can get very big very quickly. Find SuperStacks on multiple reels during the same spin and Shadow Diamond can be a real gem. If you like blingy-inspired slots, Pimped by Play ‘N Go is very entertaining but if you want high variance, NetEnt’s Piggy Riches is highly recommended.
